WATER SPRNKLER.

Application filed September 18, 1922. Serial No.`588,936.

T 0 all Lc/tom t may concern.'

Be it known that we, WILLIAM C. TODD and JAMES W. POMEROY, citizens o't'the Dominion ot Canada, residing at Victoria, in the Province of British Columbia, Canada, have invented certain new and useful lmprovements in Water Sprinklers, of which the following is a specification.

This invention relates to a water sprinkler ot that class having two sprinkler heads mounted to rotate independentlyT of one another about a common axis, and the iinproveinent is directed to a means for rotating one 01"' the sprinkler heads from the other without the use of gearing, the rotation being effected by the impact oi a jetI ot water delivered from one against a vane or impact plate connected to the other.

VThe invention is particularly described in the Afollowing specification, reference beingmade to the drawings by which it is accompanied, in which:

Fig. l is a vertical section in the axis of the sprinkler head.

Fig. 2 is a plan of the same, and

Figure 3 is a cross section taken through the pipe il at the aperture l5 and through the plate 14: and arm 7.

in these drawings Q represents a hollow spindle secured on the upper end ot an upright water delivery pipe 3, which may be mounted on a stand oi any suitable kind, and served with water through a flexible hose pipe in the manner usual with such sprinklers.

The hollow spindle 2 is axially apertured in its upper end to receive a central delivery tube l and permit that tube to turn treely, being seated at 5 to form a water-tight joint. Against this joint seat 5 the stem 4: is normally held by a radial arm 7 adjustably secured on it and by the pressure ot the water` On the head ol' the central tube el is secured an apertured nozzle cap 6.

On the hollow stem 2 a sprinkler head S is rotatably mounted, which head is chambered at 9 to receive a supply ot water from within the stem through an aperture or apertures l0 and deliver it to reaction sprinkler pipes ll secured to radially project from it and backwardly turned at the ends where the jet caps l2 aresecured on them in order to deliver the jets backward and impart the desired rotation to the head S by the reaction ot the jets.

Secured to and downwardly projecting -from the arm 7 to adjacent the path of the sprinkler pipes ll is a vane or impact plate ist. 'lf' his plate is designed to receive a jet of water from the sprinkler pipes ll as 'each one passes it. This is preferably done by providing a separate jet aperture l5 directed angularly upward toward the plate from one or all ot the sprinkler pipes 1i.

in use, the water delivered through the upright stand pipe 3 passes upwardly through the central stem f-l and is delivered through the apertures ont the cap 6. lt. passes also through the'apertures l() of the central stem 2 into the chamber 9 and there- Vfrom through the sprinkler pipes il, the escape from the caps l2 of which rotates the head S by the reaction of the jets.

As the head 8 rotates and each pipe 1l passes under the impact plate 14 of the arm 7 a momentary impulse is imparted to that arm, and to the central tube t each time the jet of water from the apertures l5 passes it.

The free rotation of an ordinary reaction sprinkler 8, 1i thus imparts a progressive, intermittent, rotational movement to the second sprinkler head e, 6, independently rotatable on the same axis. The jets of this head 6 being few and having a higher trajectory will be projected beyond the zone sprinkled by the head 8, l1 and the double head will, therefore, have an extended sprinkling area.

The device is simple, tree from the com plication of a gearing drive and is edect-ive, the head 6 receiving a practically uniform impulse as the sprinkler pipe 11 apertured at 'l5 passes under it.

Having now particularly described our invention, we hereby declare that what we claim as new and desire to be protected in b v Letters latent, is

l. A water sprinkler, comprising the combination with va freely rotatable reaction sprinkler, of a second sprinkler head independently rotatable about the same axis, said second sprinkler head having a projection adapted to be acted on by a jet from the reaction sprinkler each time that jet passes under the projection, whereby a progressive intermittent rotational movement is imparted to the second sprinkler head from the first.

2. A water sprinkler, comprising` the combination with a reaction sprinkler head freely rotatable on a hollow spindle through which it derives its water supply, of a second sprinkler head axially mounted in the upper end of the hollow spindle on which the first sprinkler head is mounted and deriving its water supply therefrom, the second head having a projection adapted to receive the impact of a jet of water from the reaction sprinkler as it rotates whereby the second head is intermittently moved through a `fraction of rotation at every impact of the passing jet. Y Y

3. A water sprinkler, comprising the combination with a reaction sprinkler head freely rotatable on a hollow spindle through which its water supply is derived, a second sprinkler head axially mounted in the upper end of the hollow spindle to rotate freely therein, an arm secured to and projecting radially from the second sprinkler head, said arm having an area exposed to the impact of a jet from the reaction sprinkler head as it rotates7 whereby the upper head on which the arm is carried is moved through a fraction of a revolution each time the jet on the reaction head passes it.

4. A water sprinkler, comprising the combination with a reaction sprinkler head freely rotatable on a hollow spindle through which it derives its water supply, one of the tubular arms of which sprinkler has an aperture directed angularly upward and forwarc toward the direction of rotation, a ser-ond sprinkler head rotatably mounted in the upper end .of the hollowspindle on which the firstsprinkler head is mounted and deriving its water supply therefrom, said second sprinkler head having a projection adapted to receive the impact of a jet of water from the forwardly directed aperture ot the reaction sprinkler head.

5. A water sprinkler, comprising the combination with a sprinkler head rotatably mounted on a hollow stem through which it derives its water supply,l a tuberotatably mounted in the upper end of the hollow Stem to be in axial alignment therewith and having a shouldered seat fitting a corresponding shoulder in the hollow stem, an apertured sprinkler head secured to the upper end of the tube, an arm removably se` cured to the rotatable tube retaining its scat in position in the hollow stem, said arm having a plate downwardly projecting from while said it adapted to receive the impact of a jet of water from one of the'tubular arms of the reaction sprinkler. I

6. A `rotatable water sprinkler, comprising the`combination with a hollow spindle on which a reaction sprinkler is freely rotatable and through which it derives its water supply, Va second sprinkler freely rotatable on the same axis and independent of the first named sprinkler, and Huid impact means for rotating the second .sprinkler intermittently through a fraction of its revolution for each revolution of the reaction sprinlder.-

7. In a rotatable water sprinkler of the character described, thecombination with a hollow spindle on which a reaction sprinkler is Vfreely rotatable'and throughwhich it derives its water supply, a second sprinkler mounted on said hollow spindle and freely rotatable on the same axis as and independent of said reaction sprinkler, and cooperative luid impact means between the two sprinklers for rotating said sprinkler intermittently from said reaction sprinkler reaction sprinkler continuously rotates.

8. AQ rotatable water sprinkler, comprising the combination with a hollow spindle, a reaction sprinkler freely rotatable on said hollow spindle and through which spindle it receives its lwater supply, a second sprinkler freely rotatable on the same axis and independent of the first named sprinkler, and means operated by impact of the fluid issuing from the reaction sprinkler for rotating the second sprinkler from the reaction sprinkler.

9. l rotatable water sprinkler comprising the combination with a hollow spindle on which a reaction sprinkler is freely rotatable and through which it receives its water supply, a second sprinkler freely rotatable on the same axis and independent of the lirst namedsprinkler, and means operated by impact of the i'iuid issuing from the reaction sprinkler' Vfor rotating the second sprinkler-through al fraction of its revolution for each revolution of the reaction sprinkler. l Y
